I am truly flabbergasted at how this could possibly be unclear still. Michael have already asked exactly the same questions in the first reply to this thread. Allow me to quote my response:

I shall go tell Default Array Property and Operator Add that, according to Martin Frb, they have been demoted from Features, because "anything he can do with you, he can already do without you" and because they need to be a "little bit more complex".

@Michael Van Canneyt: And I rest my case. /You/ never called them "default methods", but, merely based on the DEFAULT keyword and syntax similarity, users have already started calling them that -- exactly as I predicted. Then, they google "default methods" and they find "default methods in interfaces" for Java and C# -- a completely unrelated feature. Yes, the DEFAULT keyword is lying around, readily available, but is it worth the confusion of not just inventing a new term for a concept that already has an established name (cf. google "call operator overload"), but overloading the established term with an unrelated meaning?
